“In order to better evaluate the results, the performance analysis was repeated for the samples that presented the best CO2 adsorption performances (Ti/M1-P and Zr/M1-P), using longer cycles (of about 120 min for adsorption and desorption) as can be seen in Fig.14. From this figure one can find the CO2 adsorption capacity values for the samples Ti/M1-P and Zr/M1-P, which were 111.3 mg/g and 68.7 mg/g, respectively. It can be seen, from the results obtained, that the adsorption contact time initially used was not sufficient for the samples to reach their maximum adsorption capacity. It is possible to verify that the samples Ti/M1-P and Zr/M1-P presented increases of approximately 96% and 58%, respectively, in relation to the adsorption tests of the same samples performed in shorter cycles. Based on these results, it can be said that the samples subjected to longer adsorption cycles showed more satisfactory results in good agreement with the values for the CO2 adsorption capacities reported in the literature 42,58,62,65 for adsorbents similar to those synthesized in this work, although the conditions used in the experiments were different.”
